Install RVM and pre-requirements



sudo apt-get install bash curl git

bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)

Add these lines to ~/.bashrc:



# This loads RVM into a shell session.

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

Run following to test RVM and install pre-requirements specified there:



rvm notes

In my case it was:



sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev

Install default Ruby 1.9.2 and test it:



rvm install 1.9.2

rvm --default ruby-1.9.2 

ruby -v

Create project-specific gemset, make it default, install Rails with pre-requirements:



rvm gemset create my_project

rvm use 1.9.2@my_project --default

Then either create a new project:



gem install rails

rails my_project

Or install dependencies for an existing project:



cd my_project

gem install bundle

bundle install
